` Be` itknow that 1,".InssE Quarsrfuton, of Bueyrus, in the "county `ofCrawford in the State of ,0hio,

" have' invented a new andimproved Quartz0msher; Sand I' do' herebydeclare that thefollowing is a full,

clear, and exact description thereof, which will enable others skilledinthe art to make and use thesame,

. referencebeingjhadto' the ,accompanying drawing formingpartoi'this'specificaticn, inwhich- 1 Figurel represents asideelevation, partly in secf tion,` of my improved quartz-crashen Figure 2`is' a horizontal-section of the'same, taken on theplane of the-linea z,dgl-1. r, "u Similar lettersof reference indicate corresponding Thisinvention relates to improvements in quartzerushers of that kind inwhich two or more rotary crushersare employed upon a circular hed,

The invention :consists -in a` new construction of scraper, and in theapplicationV to the crusher-shals of --a series of dustfprotectors, ashereinafter more fully described.

j A, in the drawing, represents the flame of my? iins 'provedquartz-cmsher. It is made of wood, metal,or `other suitable material,`'of suitable size, and-strong enough to support themachinery which isconnected with the apparatus.

Bis the vertical maiushat of the-apparatus.` It

l "has snit-ablebearingsinrthe frame A, and receives ro- `tary motion bymeans of gearing or otherwise ,from

l the' driving-shatxa s l I) is the bed ofthe crusher. It is placedhorizontally upon the. frame A, and is made circular by mans o(projecting rim a, as shown. i

E E are .thecrushers `They are wheels made'of stone ormetal, or lined atthe edges with the latter material. l Their crushing part or main bodyis cylindrical, so that the edges are parallel, as shown. There are twosuch crusheislhnng loose upon opposite ends oi' a horizontal shaft, F.This' shaft F has an eye in the'middle, andis fitted loosely around theshaft B, so that'it may movlevupjanddown on the same, and not beaffected directly bythe rotation of the same.

`` The ends of the shaft `I are, by means of pivoted springs G G,connected with Vthe endsof arms H H, that project from the shaftBatright angles 'to F.`

The arms H are rmly attached to the shaft B,`and serve to carry theshaft F andthe crfusheis E around y with the same'.

The springs G- allow the crushersl to yield vertically to material ofvarying thickness.

II are other arms projecting from the shaft B, a

short distance above the bed D. `'.lheir ends are, by means of' cordsorv chains l), connected with the ends of a scraper, J. VJIhis scraperrests upon the bed D, and works loose around the shaft B, and is soshaped, es shown in iig. 2, as'to sweep the material onthe bed. towardvthe crushers. r

The flexible fastening b allows it to yield to unequalV s layers ofquartz.'

`'Jlhe crushers E have tubular inner projectipns c c,

emhracingthe shaft B, and serving to keep the dust from the bearings ofthe crusher.l

A hood, d, is placedoverthe arms H for the same .filled with a suitablequantity of weights, and imparts, by. resting upon the Crushers, powerto .the same. i

A metal ring, c, is secured to the under side of the` pan, to furnish anarrow support for the same on the i 'crushers, the latter, worlring ona circular path, turn quicker'o'n their outer than on their inner sides,and would, therefore, produce considerable friction on the pan L, shouldthe same rest upon the whole width of the crushers. y

When the quartz has been reduced to the required degree of iineness, aplug, j, in the bed D, is withdrawn, and thereby the upper end of aspout, g, opened.v The spout conducts the quartz into theamalgam-puniti, in which a suitable stigrer, N is set up. v

.Having thus described my invention, I claim as new and desire to securehy Letters Patent- 1. The tubes 'c c and hood d, arranged with relationto the crnshers -E E, shaft-sj?, and arms H H, as and for the purposespecified. i

2. 'lhe scraper J, constructed as shown, arranged loose on the shaft B,"andconnected with the xcd arms I of the same by means of the chains b1),as and for the purpose specified.

3. The weight-pan L c, crushers E E, shafts F B, scraper'J, arms I, bedD a, all combined, constructed, and arranged to operate as shown anddescribed.
